===Turbine engines===
[[File:Kawasaki-Honeywell T55-K-712 turboshaft Engine left side view at JASDF Komaki Air Base March 13, 2016.jpg|thumb|T55-K-712]]

Lycoming was one of the principal pioneers of turbine engines -- [[turboshaft]] to be precise—for medium- and heavy-lift helicopters, some of which have found other applications as well. Its {{convert|1400|hp|kW}}  T53 hybrid [[free turbine]] / [[shaft turbine]] engine initially powered the [[Bell UH-1|Bell UH-1 "Huey"]], and Lycoming's {{convert|4000|hp|kW}} T55 is the main power for the twin-turbine, twin-rotor [[Boeing CH-47 Chinook]]. Lycoming turbines have powered other helicopters, also.<ref name="airplanes_dawn_angelucci" /><ref name="the_helicopters_time_life"/><ref name="janes_1994_1995_p756"/><ref name="janes_1966_1967">[[John W. R. Taylor]], ed.: "AVCO Lycoming" in "USA: Engines", ''Jane's All the World's Aircraft 1966-1967,'' 1967, pp.517 et. seq., Jane's, Bucks, England, U.K. / McGraw-Hill, New York, USA</ref>

Variants and derivatives have powered various turboprop and turbofan aircraft, as well, including the [[OV-1 Mohawk]] military aircraft, [[BAe 146]] jetliner, [[Canadair Challenger]] business jet, and others.<ref name="airplanes_dawn_angelucci" /><ref name="the_helicopters_time_life" /><ref name="janes_1994_1995_p756" /><ref name="janes_1966_1967" />
